I have a 97 1/2 f150 5.4l 4wd and the blower motor went out in it no blown fuses pull motor and resistor out both bad changed still no blower motor check fuses none blown check power to blower motor none check switch in dash no power there either check fuse locations and check all fuses nothing again any thouts of what could be the problem thanks.

 

Did you check to see if the blower motor relay was doing its job?

Fuse and switch that control the relay?

Fuse that supplies the motor when the above works?

 

Yes I changed relays and re checked fuses still nothing
